  • Ferroelectric vortex-type structures have only been seen in isolated films, leaving electrode effects unexplored. Here, Peters et al. show that the polarisation curling and formation of vortex and flux-closure structures is a generic effect appearing in ultrathin ferroelectric films.

  • Metal nanocrystals are used in an ever growing list of applications, but precise control and understanding of their formation can be difficult. Here, the authors show a route that allows the controlled formation of metal nanocrystals to be carried out and observed at an atom-by-atom level.

  • Local shear stress from an atomic force microscope tip can control the crystal directions in thin oxide films. This approach enables the manipulation of local magnetic anisotropy in ferromagnetic metals.

  • Physical vapour transport is now used to grow single-atomic-layer lateral MoSe2/WSe2 heterojunctions, enabling the development of in-plane architectures for optoelectronic applications based on these semiconducting materials.

  • Analysing the structure of a PbTiO3 epitaxial layer sandwiched between SrRuO3 electrodes led to observation of a topology with two periodic modulations that form an incommensurate polar crystal, providing an analogue to incommensurate spin crystals.

  • Domain structures influence significantly the properties of ferroelectric materials. Here, the authors use phase-field simulations to show that spatially homogeneous defect charges in BiFeO3 may play a key role in the formation of the experimentally observed enigmatic zigzag domain structures, providing insights into pyramidal-domain formation in perovskite oxides.

  • Copper nanoparticles are susceptible to oxidation in air, which limits their applications. Here, the authors reveal correlations between the stability of a Cu nanoparticle and the structure of its passivating ligand, finding that short chain thiols are surprisingly more effective at retarding oxidation than longer chain ones.

  • The tetragonal tungsten bronzes are promising for high-temperature energy storage applications but the mechanisms for their broad dielectric responses are unclear. Here, a comprehensive experimental and theoretical study of Sr2NaNb5O15 explains its two large dielectric anomalies in terms of structural transitions.
